Abstract

Klordioksyd anvendes for å stabilisere hydrogenperoksyd i blekevæske ved alkalisk pH. Dette antas å hjelpes ved ødeleggelse av enzymer (spesielt katalase) som produseres av bakterier. Metoden er nyttig for reprosesserlng av masser, spesielt når et avfargings- trinn er involvert.Chlorine dioxide is used to stabilize hydrogen peroxide in bleaching liquid at alkaline pH. This is believed to be aided by the destruction of enzymes (especially catalase) produced by bacteria. The method is useful for mass reprocessing, especially when a decolorization step is involved.
